I was driving down a rural highway last week and saw catkins hanging off a tree. I hit the brakes to investigate and found several small trees right above a ditch in an old fence line. I believe that these are some type of Castanea and I assume that it is an Alleghany chinkapin, but it could also possibly be a Chinese chestnut tree. I was not able to get a photo of the trunk since it had been raining and I would have been soaked trying to get close to the trunk. The trunk was rather small (3-4 inches in diameter) and the trees were bushy and not that tall (15-20 feet) which points to a chinkapin. I should know for sure what it is in about 4-5 months when it produces seed, but I am impatient. Can anyone definitively identify the tree with just a photo of the leaves?
